Hot Launch 4 Driver
Super High MOI Design For Maximum Stability Combined With Cup Face Power
The HL4 driver features an all new sloped crown design that is deeper from face to back. No skirt where the sole plate meets the crown equates to a 12% increase in MOI over the previous Hot Launch drivers. This new design makes for an extremely high Moment of Inertia above 5000 grams per cubic centimeter making the HL4 more stable. This higher MOI will increase ball speed on miss-hits and will keep shots straighter.
Features:
- Designed with a more sloped crown that is deeper from face to back for a SUPER HIGH MOI
- Deep cup face design for exceptional power and improved acoustics
- Power Channel behind the face moves weight to back of the clubhead while also maximizing face flex
- Rear sole weight creates a deep CG and a SUPER HIGH MOI for major forgiveness on off-center hits
